Abstract: In accordance with one embodiment, the present technique provides a testing apparatus for testing material integrity in an object. The testing apparatus includes an electrical conductor and a sensing device. In the exemplary testing device, the electrical conductor extends in a generally linear direction and is configured to route current in a direction generally transverse to a longitudinal axis of the object being tested. Routing of current through the electrical conductor creates remote field eddy current effect, which, in turn, affects a magnetic field around the test object. The testing apparatus also includes a sensing device located at a distance from the electrical conductor and configured to detect magnetic fields generated in response to current routed through the electrical conductor.

Abstract: A method and system for detecting weld signatures from an ultrasound scan data obtained from scanning a pipeline is provided. The method includes a step for mapping multiple amplitude responses from the ultrasound scan data, each amplitude response being representative of a respective sensor signal. Continuous amplitude responses are located from the amplitude responses and corresponding signatures are identified for the continuous amplitude responses. The method also includes a step for tagging the corresponding signatures as weld signatures.

Abstract: An eddy current inspection system and method for inspecting a component is provided. The system includes an eddy current probe for sensing eddy currents from the component and an analog to digital converter configured for converting eddy currents to digital signals. The system also includes a processor configured for generating an eddy current image from the digital signals and pre-processing the image to enhance a quality of the image. The processor is configured to identify regions displaying flaw patterns and calculating a defect characterizing parameter for the identified regions.
